However to date there is no conclusive data demonstrating a clinical benefit of total arterial revascularization.Reports available on complete arterial revascularisation are either single institution / single surgeon, retrospective or non - randomized. Data on which we base our daily decision making is by and large from a different surgical period with different techniques used. Improved understanding of the pathogenic processes leading to graft occlusion have led to more rigorous use of antiplatelet drugs and lipid lowering which may significantly improve vein graft patency rates and slow or halt progression of native coronary artery atherosclerosis in the future.
